Dies "smite" get through walls?

does* wow nice typo >_>

I'm wonderig if smite the monk skill can get through walls like banish for example or hexes ect ect.

Does it require a clear line of sight is another way to put it?

It doesn't need a clear line of sight.

Most monk skills do not require line of sight. The actual skill "smite" does, as do a few others, like spear of light.

It's an attack skill. As such, your weapon needs to hit.

Yup. You can be stood still not attacking, and as soon as you hit smite, your wand/staff/hammer/etc will attack once doing the smite damage, and then you willl continue to attack. Smite is also effected by blindness and in answer to the original question; yes if you use smite with a projectile weapon it follows the same rules as a normal projectile.

If you look the description, Smite is attack skill and attacks always need a weapon to work. All weapons except melee weapons use some kind of projectile and projectiles need clear line of sight to hit the target.
